Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced
the first quad-channel, 16-bit analog-to-digital converter (ADC) for medical imaging
applications, such as magnetic resonance imaging (MRI). The ADS5263 meets designers’
needs for clear, crisp signals and faster acquisition times by delivering a high
signal-to-noise ratio (SNR) of 84.6 dBFS with 10-MHz input and a sampling frequency
of up to 100 MSPS. Along with high performance, the quad-channel architecture, low
power consumption of 380 mW/channel and small footprint of the ADS5263 allow engineers
to design smaller, more compact medical imaging systems than were previously possible
with existing single- or dual-channel devices. A non-magnetic package option allows
for use in a strong magnetic field, such as in MRI machines [view video].

“Medical imaging systems like MRI machines typically require
numerous high-performance electronics to achieve the clear, high-contrast images
that doctors use for early detection of diseases. The large machines often involve
a lengthy scan process, during which the patient is required to lie completely still,”
said Steve Anderson, senior vice president of TI's High Performance Analog business
unit. “Taking advantage of both our data converter expertise and our long-standing
experience in medical imaging applications, manufacturers can use the performance
and compact footprint of the ADS5263 to deliver smaller, faster equipment with outstanding
image quality for more efficient scans and increased patient comfort.”
